Tensions rise between Russia and U.S. after Black Sea drone incident.

Russia has warned the US to stop "hostile" activity near its borders after a Russian fighter jet collided with a US drone over the Black Sea. The US military said the incident was a "brazen violation of international law," but Russia denied its planes came "into contact" with the drone and accused the US of conducting surveillance near Russian airspace to help Ukraine. The incident highlights growing tensions over the war in Ukraine, with the Kremlin eager to dissuade the US from maintaining its support for Kyiv.
